Hello all. I have a X10 pro running Android 2.3.4. It's rooted and was working fine for months. I little while back (not sure exactly when), it stopped synchronizing the contacts & calendar. Upon investigation I've observed the following: There is no "Accounts & Sync" menu option in the main phone settings menu anymore The "AccountAndSyncSettings.apk" is missing from /system/app/ folder If I go to Phonebook/settings/Accounts & Sync I get a message "The application Contacts (process com.sonyericsson.android.socialphonebook) has stopped unexpectedly. Please try again" What I have tried: 1. Download the "AccountAndSyncSettings.apk" and try to install it using Apk installer. Fails saying "apk not installed" with no explanation. 2. Manually copy the AccountAndSyncSettings.apk to the system/app folder using Root Manager. I get a message that it's a read only folder. Any thoughts on what I can do?
